Hello All - I am having trouble getting the wings straight on my D-Way bowl gouge as you can see in the picture. It is 3/4" diameter with a deep U-shape. I am using my SVD-186 with hole A, P=65mm, and JS=2. To correct this, I tried to grind the wings straight on my 1750 rpm grinder, then re-shaped them with the SVD-186 and the BGM-100. Once I got close to sharp, I finished up on the Tormek SG-250 wheel. That concave wing came right back. After looking at it, I don't think it is possible to get the wings straight with the 65mm protrusion. I can't rotate the gouge far enough before it hits the support bar. With this large diameter gouge with such a deep flute, I believe that I need to move to a 75mm protrusion. I set it up this way just to eyeball the situation and it seems like this will allow me to take more steel off at the end of the wings to get me back straight.
Does this sound like the problem? Anything that I maybe missing? Thanks
